should be noted that most FES happens with femurs, but pulmonary embolism could could happen with anyone.
The second case with vinay is very rare. he had unilateral tibias done and i don't think he died from FES, but rather pulmonary emboli that reached his heart leading to heart attack. The doctors most likely did not prescribe blood thinners to help prevent this, and the pt probably was not very healthy/active if he had a previous LL on his other leg prior to this.
you want to be in the best shape you possibly can be when it comes to stamina, strength, body fat %.
you want to get all blood work done to make sure you are very healthy.
you want to choose a very good surgeon who has a track record of success when it comes to CLL
you want to make sure your doctor will prescribe blood thinners post LL or else dont choose him as your surgeon,.
you want to make sure you are as active as possible post LL. You want to try to keep your legs moving even when you are laying on the bed. You do not want to get blood clots in your legs due to immobility post surgery. This is called DVT and the blood clot from the legs can go to the heart or brain (pulmonary embolism)
also it should be noted that there has not been a case of someone dying from CLL in the united states. Also hundreds of thousands of LL surgeries are done every year due to LL discrepancies and deformities
